This is the second edition of a book that first appeared in 1962, The basic 

 organization of the book has remained unaltered, but the size has increased 

 by almost one quarter and 26 new illustrations were added. 



In the general part particularly the section on oogenesis and that dealing 

 with experimental embryology have been enlarged. In the special part many 

 minor additions have been made, partly dealing with new morphological and 

 experimental work, partly with recent biochemical findings. Entirely new 

 sections have been included on the Pauropoda and the Symphyla (Arthro- 

 poda). Throughout the book more reference is made to basic biochemical 

 and molecular-biological aspects. The selected bibliographies have for the 

 greater part remained unaltered. 



The production of the second edition is equal in quality to that of the first. 

 The subject index is more than twice as long, among other things due to 

 the inclusion of generic names.

This is an elementary textbook of animal embryology for first-year biology 

 students, and is the first of its kind to appear in Italian. It will no doubt be 

 welcomed by many University teachers in Italy, The author has aimed at 

 presenting a fairly complete survey of both general and comparative em- 

 bryology, illustrating the general principles without undue emphasis on details. 

 To instill more enthusiasm in the students he also devotes attention to the 

 basic facts of experimental embryology, ultrastructure, and molecular biology. 

 He has thus succeeded in writing a book that is modern in outlook, while 

 at the same time providing a sound morphological basis. The only area that 

 is not touched upon is developmental genetics. No literature is cited in the 

 text. 



The first chapter deals with gametogenesis, egg structure, and fertilization, 

 the second with ooplasmic segregation, cleavage, and gastrulation in diblastic, 

 holoblastic and meroblastic forms respectively. Then follows a chapter en- 

 titled "Morphogenesis", which treats the formation and differentiation of the 

 three germ layers, first generally and then comparatively. This chapter is 

 concluded by a section on causal factors in morphogenesis. 



Chapter four is devoted to the embryonic adnexa, while chapter five des- 

 cribes the general embryology of the organ systems. Chapter six then surveys 

 the development of the principal types of metazoan animals, from the sponges 

 to the chordates. A brief chapter on larval forms concludes the book. 



The book is profusely illustrated with line drawings specially prepared for 

 this purpose. They are simple but of very good quality, and clearly labeled; 

 however, several of them could have been reproduced on a somewhat larger 

 scale for greater clarity. Chapter three has a very useful chart showing the 

 comparative embryology of the mesoderm in metazoans in schematic 

 drawings. 



At the end of the book the following schemes are included: Classification
